Overview
This extension wraps the commit command to look for "smelly" changes in added code and explicitly asks the user before he can continue if such a change is found.
At the moment, this only recognizes debugging stuff that often leaks into commits in the Python language.
Configuration
Configure your .hgrc to enable the extension by adding following lines:
[extensions] hgchangelog = /path/to/hgchangelog.py
